The more you know the betterBy Svenon 11/7/2013

Not only are my 2 Dual Inline TDS meter's reading the same parameters, but I would never have realized that you need to flush the clean side of your membrane before making water without these!

I was always told just to flush your waste line... But my post Membrane Product line is around 180ppm when I first start.. After about 30 seconds of flushing the clean product line I am down to 4ppm.. I can flush my waste lane for 5 minutes and not see it drop below 100ppm... No wonder I was going through so much DI Resin

It is very important to me to know that my RODI unit is working 100% this TDS meter works perfectly, it feels good to know that the water entering is at 233 TDS and is exiting at 0. Now I will know what to change my filter media

I got one with my BRS 5 STage RO/DI unit and after a couple months is stopped working correctly. I contacted BRS and they shipped me a replacement. It was easy to install and replace. I wouldnt run and RODI without one. 4 stars bc the first one failed.

Cool product that is both useful and fun. Will help you replace filters at the right time. And it's fun to see how crappy your water coming in really is, and just how clean the water coming out is. Spend the extra $5 and get the dual unit.

Worked for about 5 days then just stopped turning on. Piece of junk product or just a lemon, but I am not happy.
